Fix Recommendation

1. Access the Tanium Server.

2. Log on to the server with an account that has administrative privileges.

3. Run regedit as Administrator.

4. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

5. Validate the value for REG_DWORD "ForceSOAPSSLClientCert" is set to "1".

6. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

7. Configure the following keys:

REG_SZ "ClientCertificateAuthField"
For example:
X509v3 Subject Alternative Name

REG_SZ "ClientCertificateAuthRegex"
For example-DoD:
.+?Name:\s*?(\S+@[._a-zA-Z0-9]+).*
Note: This regex may vary.

REG_SZ "ClientCertificateAuth"
For example:
C:\Program Files\Tanium\Tanium Server\cac.pem

REG_SZ "TrustedHostList"
For example:
Append 127.0.0.1 (for IPv4) and [::1] (for IPv6)

Check Contents

1. Access the Tanium Server.

2. Log on to the server with an account that has administrative privileges.

3. Run regedit as Administrator.

4. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

5. Validate the value for REG_DWORD "ForceSOAPSSLClientCert" is set to "1".

6. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

7. Validate the following keys exist and are configured:

REG_SZ "ClientCertificateAuthField"
For example:
X509v3 Subject Alternative Name

REG_SZ "ClientCertificateAuthRegex"
For example-DoD:
.+?Name:\s*?(\S+@[._a-zA-Z0-9]+).*
Note: This regex may vary.

REG_SZ "ClientCertificateAuth"
For example:
C:\Program Files\Tanium\Tanium Server\cac.pem

REG_SZ "TrustedHostList"
For example:
127.0.0.1 (for IPv4) and [::1] (for IPv6)

If the value for REG_DWORD "ForceSOAPSSLClientCert" is not set to "1" and the remaining registry values are not configured, this is a finding.
